STRAW' BAND FOR THE MANUFACTURE OF CIGARETTE MOUTHPIEGES.

Application filed November 13, 192A, Serial No. =749,7.25, and in Germany October 8, 1924.

This invention has for its object a strawband for the manufacture of cigarette mouthpieccs and other articles in the straw industries, this straw-band consisting of a band of tissue paper, linen or any other suitable material and length, and of slit-up and fiat-spread-out straw tubes attached to the tissue paper band in the manner hereinafter described. My improved straw-band is distinguished from other known bands made of paper and formed into tubes, or from known straw-bands in which the slit and spread out straw tubes glued on the strip of tissue paper or other material have been utilized as cigarette mouthpieccs, in that its manufacture is considerably simplilied and cheapcned thereby, that for the making of the finished band subsequently rolled on a spool, reel or the like, the slit and flat-spread straw tubes are directly glued lengthwise and in parallel rows upon a basc-band of tissucpaper, linen or other suitable material, the fibres running in the direction of the said band. The width of the latter may be equal to that of bands for cigarette making machines usually used, or it may be or is made several or even a great many times that width. In the latter case it is then necessary by means of a suitable 39 cutting machine to cut the rolled-up band into the correspondingly small bands.

A feature of novelty in my invention, as compared with known straw-bands wherein the ends of the slit and flat-spread straw tubes are caused to overlap and are glued together, is that the armour-like skin of the straw tubes at the places to be glued is removed, for instance by means of grinding tools, whereby not only a rough face for the sticking on of the glue is provided, but also a reduction of the thickness of the glued joint obtained. The straw tubes may either be treated singly in the manner described, or they are arranged in rows on wide tissuepaper bands or linen strips in the form of straw plates.

In the accompanying drawings:

Fig. 1 shows diagrammatically a small portion of the length of a base-band and straw tubes thereon of a width several times that of the band usual in cigarette making machines.

Fig. 2 shows also diagrammatically a short length of a modified form of the tissue-paper base-band with the slit-up and spread-out straw tubes, this band being of the usual width;

Fig. 3 shows diagrammatically a third modification of the arrangement of the slitup and spread-out straw tubes on the baseband;

Fig. i is a longitudinal section, on an enlarged scale, through the joint of two in the same line lying, slit-up and spread-out straw tubes according to the form shown in Fig. 2, and

Figs. 5 and 6 are cross sections through the lines AB and CD in Figs. 1 and 2 respectively, the bands being shown in perspective.

Referring to Figs. 1 and 5, there are gummed on the endless base-band 1 of tissuepaper, linen or any suitable material of any desired length and a width several times that of the base-band usually used in a cigarette making machine, a series of slit and flat spread-out straw tubes with the fibres thereof running longitudinally in the direction of the aforesaid band, in such. a manner, that longitudinally disposed rows a a a b 5 o of the straw tubes are formed of which the oints lie flush in aline and below each other. Subsequent to the winding or rolling upon a spool or roller of any suitable size of the thus gummed strawband, the latter is cut through by a cutting device on the lines 1-1, IIII and IITIT1, and in this way divided into the separate smaller bands. These bands, in turn, are then cut in strips of any suitable length and made to form mouthpieccs for cigarettes of the required size.

According to the modification, Figs. 2 and 6, I provide a base-band 1 which corresponds with the width of the band commonly known in cigarette making machines. The slit and flat spread-out straw tubes a a 6 b 0 0 however, are in this case and preferably in all forms ground at their joining ends and reduced as shown in Fig 4 on a large scale, the slit and spreadout straw tube a by means of known grinding tools, being ground on the armour-like upper face and the other straw tube a on the also armour-like underface. The joints of the flattened straw tubes are therefore forming an even surface with the other parts thereof and consequently allow of an easy and smooth winding up on a spool or roller of the straw-band.

According to the modification, Fig. 3, there is again provision made of a base-band 1" of a width several times that of a usual band, the novel feature in this modification being that the straw tubes are so placed that the joints a: of one of the straw tube rows are set off against those 1 of the neighboring straw tube. It will be understood that also a band, such as shown in Fig. 2, may have the straw tubes gumn'ied and arranged in the same way as described with reference to Fig. 3.

vFor the removal of the silieic acid cover a grinding-wheel may be employed, the axle thereof being mounted parallel to the fibres of the straw tubes. The latter or the joined straw tube plates are hereby moved under the grindingwheel and laterally of the direction of the straw fibres, or, the said grinding wheel may be moved along the ends of the straw tube or plate and laterally of the fibres. In place of the joining of the straw tubes by glue, they may also be connected by surface attachment, for instance by causing the straw tubes to be drawn through the relief rollers known for such purposes. It is also possible to combine both n'icthods of connection.

This improved method is not only adant ed for the making of cigarette month-pieces, but it can also find use not only in the mannfzzcture of straw hats and the whole of the strznv-working industries. As tests have shown the bands at the connecting places of the straw tubes have a great strength of extension and exceed in this respect the known bands in which the straw tubes or strips of a straw tube plate are connected at their ends by gumming lashes.

What I claim as new and desire to secure by Letters Patent is 1. A strawband comprising a base of sheet material bearing upon one of its surfaces a row of flattened straw strips arranged in parallel relation with their longitudinal edges abutting, said strips having roughened bot-tom faces formed by the removal of the natural hard skin coating thereof, whereby thinned strips of increased flexibility are produced, said roughened faces of the strips being cemented to the said base of sheet material. a a x 2. A strawband comprising a base of sheet material bearing upon one of its surfaces a plurality of transverse rows of flattened straw strips, the strips of each row having their longitudinal edges abutting and the strips of the several rows being disposed in longitudinal alinement and having their end edges abutting, said strips having roughened bottom faces formed by the ren'ioral of the natural hard skin thereof, whereby thinned strips of increased flexibility are produced, said roughened faces of the strips being cemented to the said base of sheet material.

3. A strawband con'iprising a base of sheet material. bearing upon one of its surfaces a plurality of rows of flattened straw strips, the strips of each row having their ends reduced and overlapping within the thickness of a strip, and the strips of the several rows being disposed in parallel relation with their longitudinal edges abutting, the abut ting ends of the strips of each row being arranged between and in break-joint order with the abutting ends of the strips of an adjacent row or rows, the said strips of the rows being reduced to less than normal thickness by removal of the hard natural skin from the bottom surfaces thereof. leaving said surfaces roughened, said roughened surfaces being cemented to the sheet of base material.
